2 Claims.

This invention relates to a carburetor, the general object of the invention being to provide means whereby compressed air is thoroughly mixed with liquid fuel to provide a practically dry vapor.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accomlO panying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding l5 parts throughout the several views, and in which:-

Figure 1 is a fragmentary vertical sectional view showing the invention in use supplying a mixture to a house or the like.

2'0 Figure 2 is a longitudinal sectional view through the device.

Figure 3 is a 'section on the line 3 3 of Figure 2.

Figure 4 is a section on the line 4 4 of Fig- Ure 2.

Figure 5 is a fragmentary longitudinal sectional view through Figure 2 showing one of the conical members.

In these drawings, the numeral I indicates a tank which contains liquid fuel of any suitable kind such as pentane and the numeral 2 indicates an elongated cylinder passing through the top of the tank where the cylinder is threaded to the tank by the threads 5 and the lower end of the cylinder is located close to the bottom of the tank and said lower end of the cylinder is closed by the closure part, provided with the perforations 6 for permitting liquid fuel to enter the cylinder. An inverted conical member 'I is placed in the lower part of the cylinder slightly above the bottom thereon and this member is also perforated as at 8 to permit the liquid fuel to pass through the same.

The upper end of the cylinder is provided with a cylindrical enlargement 9 `which is located above the tank and a pipe I0 passing into the part 9 on the side thereof and is then bent at right angles with the bent portion passing through the cylinder 2 to a point close to the apex of the cone 'I. Spaced perforated plates II are carried by the cylinder and act as ysupporting means for the pipe and a plurality of spaced con-l ical screens I2 encircle the pipe at the small end 65 with their lower and large ends contacting the internal wall of the cylinder. Some of these screens are of larger size, as shown at I 2 and are placed in the pipe in the enlargement 9. These screens can be made of fine copper wire or mineral wocl or any other useful material, which will act to break up the liquid fuel and to cause the gas to thoroughly mix with the compressed air which is introduced into the device through the pipe I0 from a tank I3 by a pipe I4 connected to the upper end of the pipe I0 as shown at I5, said pipe I4 containing a check valve Ilf. a A motor driven compressor I'I is shown in Figure 1 for supplying compressed air to the tank I3 but it will, of course, be understood that any suitable means may be used to supply 15 compressed air to the device. The mixture of liquid fuel and air is led to the furnace of a dwelling or any other suitable building by a supplypipe I8 connected with the upper end of the part 9 and containing a check valve I9 and other 20 valves may be placed wherever desired in the supply pipe, one of these valves being shown at 2U in Figure l.

Thus it will be seen the compressed air flows down the pipe I0 and escapes adjacent the apex 25 of the cone 'I which directs the air upwardly and the liquid fuel entering the lower part of the cylinder 2 through the perforations 6 and 8 will mix with the compressed air and as the mixture passes through the perforations of the plates II, 30 and the meshes of the screens I2 the mixture will be thoroughly mixed together and will thus pass from the device ready to be burned. I'he mixture will be under pressure so that it will be supplied to the burners with sufficient pressure to burn 35 readily.

It is thought from the foregoing description that the advantages and novel features of the invention will beV readily apparent.

It is to be understood that changes may be 4o made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed isz- 1. A device of the class described comprising a tank containing liquid fuel, a cylinder extending into the tank from the top thereof to a point close to the bottom thereof, said Vcylinder being 50 in communication with the tank at its lower end, the rest of the cylinder being out of communication with the tank and the upper end of the cylinder forming a chamber, a pipe extending through the cylinder to a point close to the lower end thereof, means for supplying compressed air to the pipe, conical screens placed in the cylinder and surrounding the pipe and having their large lower ends contacting the walls of the cylinder and an outlet pipe leading from the chamber.

2, A device of the class described comprising a tank containing liquid fuel, a cylinder entering the top of the tank and extending to a point adjacent the lower end thereof, the lower end of the cylinder having openings therein, an inverted conical member in the lower part of the cylinder having perforations therein, a pipe passing downwardly through the cylinder to a point adjacent the lower end of the conical member, means for introducing compressed air into the pipe, perforated suppo-rting plates in the cylinder for the pipe, a plurality of conical screen members having their small ends surrounding the pipe and the large lower ends contacting the internal walls of the cylinder, a large cylinder at the upper end of the rst cylinder located above the tank and through a portion of which the pipe passes, large conical screen members located in the large cylinder and surrounding the pipe and a discharge pipe leading from the large cylinder.
